NutriTune

Import any recipe — even straight from Safari — then fine-tune ingredients on the Mixing Desk and watch your macros update live, down to the gram.

OVERVIEW NutriTune turns any recipe into precise, adjustable nutrition — paste text, paste a URL, scan a printed recipe with your camera, or share straight from Safari. No account or sign-in required.

QUICK START

1. Import a recipe — paste text, paste a URL, snap a photo, or share from Safari
2. Review the ingredient matches — NutriTune matches each one to a nutrition database and flags anything worth double-checking
3. Open the Mixing Desk to see the full nutrition breakdown
4. Long-press any ingredient to fix a match, set an exact amount, or edit its details
5. Drag a slider — or tap the percentage and type a number — to adjust an ingredient and watch every macro update instantly
6. Adjust servings with one tap; everything recalculates automatically
7. Save your changes, then come back to cook

CORE FEATURES

• Import by pasted text, URL, camera scan, or Safari's Share Sheet, with a notification that brings you straight back to finish importing
• Automatic ingredient matching against a nutrition database of 1,000+ items, with confidence flags on anything uncertain
• Long-press an ingredient to fix a match, rename it, or edit its details — no extra screens
• The Mixing Desk: adjust any ingredient by slider or by typing an exact amount or percentage, with live-updating macros and calories
• Lock Flavours: spices, aromatics, and other flavor-defining ingredients default to locked against casual scaling, so a dish's balance stays intact
• Accurate gram conversion based on each ingredient's real density and piece weight, not a flat guess
• Supports both British and American recipe wording and units
• Metric and Imperial unit display, your choice
• A short walkthrough on first launch, replayable anytime from Settings

TECHNICAL

• Built with SwiftUI
• No account, cloud backend, or authentication
• No analytics, tracking, or third-party SDKs
• All nutrition calculations and recipe parsing run on-device
• Metric and imperial units

PRIVACY

• Zero data collection, no analytics or tracking
• No third-party services
• Recipe text and camera scanning are processed entirely on-device
• Importing a recipe by URL fetches that page directly from the source website you provide — no other network use
• Recipes are stored only on this device — there's no account, cloud backup, or sync, so losing or resetting your device without transferring it first means your recipes aren't recoverable

TARGET USERS Fitness enthusiasts, meal preppers, athletes, diet-conscious individuals, health-conscious cooks.

PROBLEM Tracking macros across a full recipe is tedious, and getting it wrong is easy — a scaled-up batch or a swapped ingredient can throw off your numbers without you noticing. NutriTune gives you a per-recipe nutrition overview and lets you adjust ingredients while watching the macro impact live, so you can dial in a recipe without losing its intended taste profile or its nutritional accuracy.

USE CASES

• "If I reduce the oil, how do the macros change?"
• "Adjust this recipe for 7 people instead of 4"
• "How much does swapping this ingredient change the protein?"
• "I found a recipe in Safari — get it into my tracker in two taps"
